Earlier: A mass shooting at Umpqua Community College in Roseburg, Oregon, left 13 dead and reportedly more than 20 injured on Thursday, according to CNN. Police responded to reports of a shooting at the school just before 11 a.m. Thursday morning, and Oregon State Police spokesman Bill Fugate told CNN that the shooter has been detained, so it's no longer an active shooting situation. It's unclear whether or not the suspect was injured. Agents from the U.S. Bureau of Alcohol, Tobacco, Firearms, and Explosive were quickly at the scene, and canines teams were sent to search for explosives, guns, an ammunition. Victims of the Umpqua shooting are still being identified, though NBC News reported that at least one woman was shot in the chest.

Douglas County Fire Marshal Ray Shoufler told CNN: "We arrived to find multiple patients in multiple classrooms. Law enforcement was on scene and had the shooter neutralized." Shoufler also told CNN that two people died on the way to the hospital and The Oregonian reported that there were at least six critically injured victims.

According to The Oregonian, victims would probably be taken to hospitals in Eugene and Springfield. Jim Godbold, director of communications at PeaceHealth Riverbend Hospital in Springfield, told The Oregonian: "We're trying to prepare for a half dozen or more victims ... This is a disaster level response."

Kortney Moore, an 18-year-old Umpqua student, told the local News-Review Today that she was in a writing class when a gunshot came through the window. She said the shooter then came into the classroom, shot the teacher in the head, and opened fire on students. Moore told News-Review Today that she was lying next to people who had been shot.

Umpqua is a two-year school with about 3,300 full-time and 16,000 part-time students, located roughly 180 miles south of Portland in the North Umpqua River Valley. Uninjured students and faculty were bused to the nearby Douglas County Fairgrounds, where friends and family were told to meet them.

As of now, no info on the identity of the victims has been released. Check back for updates.
